HINGE.

Specification of Letters Patent No. 82,482, dated June 11:, 1861.

To all whom 'it may concern: j

Beit known thatI,O. M. LANE, of Cincinnati, in the county of I-Iamilton and State of Ohio, have invented a new and Improved Hinge; and I do hereby declare that the H following is afull, clear,land exact description thereof, reference being had to the acaccompanying drawings, making part of this specification, in which- F ignre l, shows the two parts of my improved hinge when put together. Fig. 2, shows the parts detached. Fig. 3, is a vertical'section through the eyes and pins of u my improved hinge. Fig. 4C, is a horizontal section in the Fig. l.

Similar letters of reference indicate cor-` responding parts in the several figures.

This invention relates to an improvement in the loose-joint butt-hinges.

It consists in casting or otherwise forming on the leaves of the hinge two or more pins and corresponding socket bearings for said pins, either by forming the pins on one leaf and the socket bearings on the other leaf of the hinge, or by forming a pin and a socket on one leaf, and. a corresponding socket and pin on the other leaf, thereby combining the advantages of a tight joint hinge with a loose joint hinge, as will be hereinafter described.

To enable those skilled in the art to make and use my invention I will proceed to describe its construction and operation.

In the accompanying drawings A, represents one leaf of the improved hinge and B, is the opposite leaf. On leaf A, two cylindrical portions a, b, are formed, the portion a, has a deep socket in it open at the upper end only; and the portion b, has a strong cylindrical pin' c, formed on its upper end. Leaf B, is made like the leaf A, the

plane indicated by red line m, a2,

' difference being only in the arrangement of the pin and socket. The socket portion cl, of leaf B, is opposite the pin carrying portion b, of leaf A, and the pinl c, of leaf B, is opposite the socket portion a, of leaf A, as clearly shown inFigs; l, and 2, of the drawings. The pins c, yand e, of the cylindrieal portions b, and g, are formed in easting the leaves of the hinge and so also are the sockets into which these pins lit. The space between the end of pin 0,"and eylin* drlcal portion a, is such as to allow the socket portion d, of leaf B, to be passed over the pin c, and the pin e, to be passed over socket portion a, in putting the leaves of the hinge together. New instead of forming a pin on one leaf and a socket on the other leaf, both pins may be formed on one leaf to fit into two sockets on the other leaf, but in the plan shown and described above there is an advantage obtained in matching the leaves, as any two leaves or halves of the same pattern will form a perfect hinge and a good joint'.`

In very long hinges if found desirable several pins with corresponding sockets may be used to still further increase the strength of the hinge but for` all ordinary sized hinges the two. pins and sockets, one at the t-op. and the other at the bottom of the leaves,

will possess sufficient strength.

The pins c, and e, in my hinge can be formed slightly conical or tapering from the ends of their cylindrical portions to their points. This will give a greater body of metal where the greatest strain is felt and consequently increase the strength of the pins. l

W'hen the leaves of the hinge are put together, by inserting the pins c, e, in their respective sockets, the lower ends of the portions g, and CZ, will bear on the upper ends of their respective portions a, and b, as in the common fast-joint hinges where a pintle is used, the strength of the tight joint hinge will thus bel obtained, combined with all the advantages of the loose joint hinges.

vOne important advantage in my improved hinge which adds greatly to its strength, consists in forming the bearings near the ends of the hinge, instead of the center as on the old loose joint hinge. Another advantage equally important, which also adds to t-he strength and durability of the hinge, consists in doubling or trebling the number of bearings; as, for example, a heavy door hung with three of my' three pintle hinges, would have nine bearings to receive its weight and consequent wear, while with the old loose joint hinge the same number would give butthree bearings.

The old loose joint hinge is. seldom used on heavy doors, on account of its liability tof wear, and the diiiiculty hanging heavydoors with 1t. Having .but one bearing itis difficult to keep. 1n line, and very liable to be broken -or wrenehed` olf by the slightest `I deviation of the top or bot-tom of-the door.

The same difficulty is experienced in removrehanging when desired, as great care is required lest the hinge be broken, by one of.

`the pintles being in its socket whilet he other is'out. All these objections and difficulties are remedied in my improved hinge, by ha'ying the bearings increased in number and placed at the top and bottom of the hinge, 4thereby giving the door or shutter to which it is attached much greater support, which may be opened or shut on one hinge alone without injury. There is also an important advantage in casting over all cast iron hinges; as by reference to the drawings it will be seen, that only one pattern is required to cast both leaves of the hinge, thereby saving largely in patterns,

as also inlabor of sorting and matching.

It has also an advantage over all other j hinges 1n breakage, as however many may be broken there can never be but one odd leaf if any, as any two leaves t each other equally well, whereas with the old loose joint hinge the pintle leaf being most liable to be broken, large-quantities of unmatched halves 25 are constantly on hand.

I am aware that the single pin and 4socket joint hinge is not new, and I therefore disclaim it; but

What I do claim as new, and desire to 30 secure by Letters Patent is,

A hinge constructed substantially as described, consisting of two or more pintles and sockets, or bearings, when combined with a loose joint hinge, or a hinge the two 35 parts of which maybe lifted on or loffv at pleasure.
